Car Sort: Color Puzzle Level 455 Solution Walkthrough
Route Reference
Key opening, middle, and finish positions for this route.

Read The Two Entrances
The opening shows red, blue, beige, purple, brown, green, pink, white, and cyan. A tall blue column stands in the center, while the black panel below it controls the lower road. Left and right bottom columns wait behind counters.
Use this route reference:
top red/blue release -> beige left column -> purple right column -> brown and red bottom-left -> pink left side -> green right side -> white lower-right -> blue center cleanup -> final purple and cyan
The central blue column is the main checkpoint. Do not flood the bottom while that column is still locked.
Open The Upper Entrances
Start with the top red/blue groups. They clear the upper road and lower the first counters. Beige on the left becomes safe next. Purple on the right follows after beige because both use the central road.
Brown and red from the bottom-left become available once the center panel drops. Clear brown first if it is closest to the road, then red. These releases open the lower side.

Work Around The Blue Column
Pink on the left side helps expose the central area. Green on the right becomes safe after pink and red have moved. White from the lower-right should wait until green leaves, because white needs the same right bend.
Blue in the center is the big late release. Move it when the column is fully exposed and the road is empty. If blue is split by the lock board, finish the nearby counter color first.
Final Cleanup
Purple and cyan usually finish the level. Clear purple if it is attached to the right-side entrance, then cyan from the top or lower-right. The completion prompt appears after the central column and lower-right column are dark.
Recovery Notes
If the center does not open, finish top red/blue, beige, or purple. If the bottom stalls, complete brown, red, green, or white before moving the center blue column. Level 455 is a center-column puzzle: unlock the entrances, clear the sides, then release blue and the final cool colors.
Center Column Checkpoints
The opening checkpoint is simple: both upper entrances should be active, but the central blue column should still be protected by the black panel. After red/blue and beige move, purple on the right should become the bridge into the bottom-left colors. Brown and red then open the lower side.
The middle checkpoint has pink on the left, green on the right, and white waiting lower-right. This is the point where many mistakes happen. Do not release white before green has cleared the right bend. White needs a clean road and will otherwise sit behind green traffic.
When the central blue column finally opens, give it the entire route. It is the longest late batch and should not share the road with purple or cyan. After blue, the remaining purple/cyan cleanup is short and safe.
